if it's a gift there is no tax on the first $11K, but only individuals and married couples can gift to other individuals so moot point. This is a prize won in a contest so its considered income and taxable at whatever the winners tax rate is. The tragedy would be if this $10K prize bumped him up to the next bracket.
BTW no one noted the irony of the winning song title.
LOL, I guess I will be first to pay respects to the loser. Why can't Apple just give away a cash prize?
